E. Revocation of election
An election not to use reserve days may be revoked in whole or in part (subject to the restrictions in C. above) while the patient is still in the hospital or within 90 days following discharge provided a claim has not been filed for Part B ancillary services furnished on the hospital days in question. The revocation must be submitted to the hospital in writing and made part of the patient's hospital record. If a beneficiary is incapacitated, any of the individuals who are permitted to sign the Request for Payment may file the revocation on the beneficiary's behalf within the 90 day period. However, an election not to use reserve days may not be revoked after the beneficiary dies.
